Prokaryotic vs. Eukaryotic cells Flashcards
What is a prokaryotic cell?
A type of cell that lacks a membrane-enclosed nucleus and membrane-enclosed organelles.
What is a eukaryotic cell?
A type of cell that has a membrane-enclosed nucleus and membrane-enclosed organelles
What is a nucleoid?
It is an unbound region where the prokaryotic cell’s DNA is located.
What are the basic features of all cells?
All cells contain chromosomes, have ribosomes, have a plasma membrane, & have cytosol inside.
What is a nucleus?
It is an organelle of a eukaryotic cell that contains the genetic material.
What is a cytosol?
It is a semifluid, jellylike substance in which subcellular components are suspended.
Which is larger: eukaryotic cells or prokaryotic cells?
Eukaryotic cells are generally much larger than prokaryotic cells.
What two domains have prokaryotic cells?
Domain Archaea and Bacteria
What domain has eukaryotic cells?
Domain Eukarya
What is cytoplasm?
It is the interior of the cell. In prokaryotic cells, cytoplasm is bounded by the plasma membrane. In eukaryotic cells, it is bounded by the plasma membrane and nucleus.
What is a plasma membrane?
A selective barrier that allows passage of enough oxygen, nutrients, and wastes to service the entire cell.
What structures are in animal cells, but not plant cells?
Lysosomes, centrosomes, and flagella
What structures are in plant cells, but not animal cells?
Chloroplasts, central vacuole, cell wall, plasmodesmata
